TO ALL WHOM ITKMAY CONCERN; p v

Be it known that I, JAMES E. Corton, of the cityI of Brooklyn,-in the State of New York, have invented a certain new and useful Improvement on Lever- Presses for manufacturing tin-ware; andI do hereby declare that the following is a full, clear, andexact description of the'construction and operation of the same, reference being had to the accompanying drawings and to the letters and marks thereon, which said drawings formV part' of this specilcatiomand show a lever-press, and parts thereof, constructed under my invention- Figure 1 being a side view, Y Figure 2 a top view, and Figure 3 a bottom view of such press. l In all these figures, where like parts are shown, like marks and letters are used to indicate the parts.

In presses of this kind, it is very important that the dies for punching, cutting out, and swaging the Isheet metal into form, should be accurately adjusted and ittedto the mandrel and to the bed. It is also important that the mandrel be' worked true and smooth in its hearings or supporting heads. I Y,

In cutting out irregular forms, it is desirable that the bed, on which rests the lower die, be so constructed and arranged that it may be turned or`rotated on the frame-plate or arms supporting it, so that the lower die may beaccurately'adjusted to the upper die attached; tothe mandrel, and perfect and smooth cutting and swaging thereby produced. l

The bed a of this press is connected to the frame-plate or arms 6 by screw-bolts c and nuts d,'the lower ends e ofthe'bolts being anged, so Athat they Vlap over the inner edgef of the 4curved slots yin the frame-plate-b.

Two lscrew-bolts and two slots are shown by the drawings, but there may be three or four. l l

This manner of attaching the bed to the plate or arms oi' the machine allows of its being moved around entirely or rotated, and the lower die'perfectly adjusted to the upper die,' without disturbing the connections between the die and the bed, as simply detaching the nut-s and bolts leaves the' bed free to be moved in any direction. The mandrel L has a broad face, z', andbroad bearing in the lower head j, but is narrowed or contracted above, so that its upper end is much smaller than the lower. A saving in metal is thus effected, and less friction produced in the upper head than if the mandrel were of the samc'width above as below. The sides ofthe mandrel working in the lower head are recessed, 7c, for the tting therein of theinner surfaces ofthe;

headso that very true and smooth working ot' the mandrel is insured. The `mandrel is.` operated by the lever l, upright bar m, and treadle mas is is very clearly shown by tlg. 1 ol' the drawings. I

What I claim as my invention, and desire to secure by Letters Patent, is The arrangement of the bed a upon the plate b of the machine, and the mandrel h in the upper and lower heads, with the leversfor operating the mandrel, as hereinlset forth.

This specification signed, this 21st day o'f April, 1868. l l
